The monkey in the tree!
A monkey is sitting in a tree smoking a joint when a lizard walks past, looks up, and says to the monkey, "Hey! What are you doing?"
The monkey says, "Smoking a joint, Come up and have some."
So the lizard climbs up and sits next to the monkey, and they share a few puffs.
After a while the lizard says his mouth is "dry" and is going to get a drink from the river.
Once at the river, the lizard is so stoned that he leans too far over and falls into the water.
A Crocodile sees this, swims over to the lizard, and helps him to the side; then he asks the lizard, "What's the matter with you?"
The lizard explains to the crocodile that he was sitting smoking a joint with the monkey in the tree, got too stoned,
and then fell into the river while taking a drink.
The crocodile says he has to check this out and walks into the jungle, finds the tree where the monkey is sitting,
finishing a joint, and he looks up and says, "Hey!" The Monkey looks down and says, "Duuuuuuuuuuuuuuuuuuude! How much water did you drink?!"
